Use Deaths web, why?
A. Your attacks are not fcr dependant, and hoto offers less +skills than a deaths web could. Death web also speeds up your killing insanely
B. Hoto offers relatively little resistance for the item slot. You could sacrifice your shako/other helm for a good kiras for more of a resistance gain and at a lower sacrifice in damage.
FCR isn't very necessary i've found. I've hit the 48% fcr bp while still maintaining good damage (63% fcr is for a sorc evild2player

) and it can be tedious,
and for a venomancer in my experience it isn't worth the trouble, even with teleport. For higher breakpoints you'd have to get rid of 3 piece trang, and I don't feel it is worth that, since -resistance is the most important attribute of a venomancer.
Enigma breast plate all the way, base strength.
